2.1 查看鏡像
[root@localhost ~]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/hello-world latest 05a3bd381fc2 5 weeks ago 1.84 kB
選項說明:
REPOSTITORY：表示鏡像的倉庫源
TAG：鏡像的標簽
IMAGE ID：鏡像ID
CREATED：鏡像創建時間
SIZE：鏡像大小
同一倉庫源可以有多個 TAG，代表這個倉庫源的不同個版本，如ubuntu倉庫源裏，有15.10、14.04等多個不同的版本，我們使用 REPOSTITORY:TAG 來定義不同的鏡像。

2.3 下載鏡像
[root@localhost ~]# docker pull centos ##下載centos鏡像 Using default tag: latest Trying to pull repository docker.io/library/centos ... latest: Pulling from docker.io/library/centos d9aaf4d82f24: Pull complete Digest: sha256:eba772bac22c86d7d6e72421b4700c3f894ab6e35475a34014ff8de74c10872e [root@localhost ~]# docker pull nginx ##下載nginx鏡像 Using default tag: latest Trying to pull repository docker.io/library/nginx ... latest: Pulling from docker.io/library/nginx bc95e04b23c0: Pull complete 110767c6efff: Pull complete f081e0c4df75: Pull complete Digest: sha256:004ac1d5e791e705f12a17c80d7bb1e8f7f01aa7dca7deee6e65a03465392072 [root@localhost ~]# docker images ##查看現有鏡像 REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/nginx latest 1e5ab59102ce 2 weeks ago 108.3 MB docker.io/centos latest 196e0ce0c9fb 5 weeks ago 196.6 MB docker.io/hello-world latest 05a3bd381fc2 5 weeks ago 1.84 kB
2.4 導出鏡像
## docker save -o [鏡像名稱] [鏡像]
[root@localhost ~]# docker save -o centos.tar.gz centos [root@localhost ~]# ls anaconda-ks.cfg centos.tar.gz #需要將docker導出為tar.gz，後面為鏡像名稱 [root@localhost ~]# docker save centos > /opt/centos.tar.gz [root@localhost ~]# ls /opt/ centos.tar.gz
2.5 導入鏡像
[root@linux-node1 ~]#docker load --input centos.tar #使用input導入 [root@linux-node1 ~]# docker load < nginx.tar #使用重定向導入 [root@linux-node1 ~]# docker load < /opt/centos.tar.gz #導入本地鏡像到docker鏡像庫
2.6 刪除鏡像
##docker刪除可以使用docker rmi 後面加上docker的ID
[root@linux-node1 ~]# docker images ##查看鏡像 REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/nginx latest abf312888d13 2 weeks ago 181.5 MB docker.io/centos latest 0584b3d2cf6d 6 weeks ago 196.5 MB [root@linux-node1 ~]# docker rmi abf312888d13 ##刪除鏡像 提示：如果鏡像已經創建了一個容器，那麽將無法進行刪除 Untagged: docker.io/nginx:latest Deleted: sha256:abf312888d132e461c61484457ee9fd0125d666672e22f972f3b8c9a0ed3f0a1 Deleted: sha256:21976f5d6f037350c076d6974b2ac97777c962869d5511855170dc5c926d5aac Deleted: sha256:f9719c3716279b47727a51595d1482506be469c581383cb529f4005ba9bf2aeb Deleted: sha256:fe4c16cbf7a4c70a5462654cf2c8f9f69778db280f235229bd98cf8784e878e4 [root@linux-node1 ~]# docker images ##查看鏡像 REPOSITORY TAG IMAGE ID CREATED SIZE docker.io/centos latest 0584b3d2cf6d 6 weeks ago 196.5 MB
